Many people ask, why do a stealth run over a normal run, here are the reasons.
Alternative to the normal instance grind
Easier to farm certain items
Can do it in smaller groups
I’ve also met quite a few people that don’t like stealth runs as they think they end up taking as long or longer than a normal run. This can be true, just as it can be true you get a nub group that can’t finish an instance. A smooth stealth run, with experienced runners will go quicker then a normal run, but one misstep, and someone that has to do a graveyard run, can indeed drag out the time it takes to finish the instance.
